System operation

WARNING
The Distance Control Assist system automatically decelerates your vehicle to help assist the driver to maintain a following distance from the vehicle ahead. Manually brake when deceleration is required to maintain a safe distance upon sudden braking by the vehicle ahead or when a vehicle suddenly appears in front of you.

Always stay alert when using the DCA system.

The Distance Control Assist (DCA) system helps assist the driver to keep a following distance to the vehicle ahead by braking and moving the accelerator pedal upward in the normal driving condition.

When a vehicle is detected ahead:

The vehicle ahead detection indicator comes on.

When vehicle approaches a vehicle ahead:

● If the drivers foot is not on the accelerator pedal, the system activates the brakes to decelerate smoothly as necessary. If the vehicle ahead comes to a stop, the vehicle decelerates to a standstill within the limitations of the system.
● If the drivers foot is on the accelerator pedal, the system moves the accelerator pedal upward to assist the driver to release the accelerator pedal.

When brake operation by driver is required:

The system alerts the driver by a warning chime and blinking the vehicle ahead detection indicator.

If the drivers foot is on the accelerator pedal after the warning, the system moves the accelerator pedal upward to assist the driver to switch to the brake pedal.

The stoplights of the vehicle come on and the brake pedal depresses when braking is performed by the DCA system.

When the brake operates, a noise may be heard. This is not a malfunction.

WARNING
● When the vehicle ahead detection indicator light is not illuminated, the system will not control or warn the driver.
● Depending on the position of the accelerator pedal, the system may not be able to assist the driver to release the accelerator pedal appropriately.
● If the vehicle ahead comes to a standstill, the vehicle decelerates to a standstill within the limitations of the system.

The system will release brake control with a warning chime once it judges the vehicle is at a standstill. To prevent the vehicle from moving, the driver must depress the brake pedal. (The system will resume control automatically once the system reaches 3 MPH (5 km/h)).

Overriding the system:

The following drivers operation overrides the system operation.

● When the driver depresses the accelerator pedal even further while the system is moving the accelerator pedal upward, the DCA system control of the accelerator pedal is canceled.
● When the drivers foot is on the accelerator pedal, the brake control by the system is not operated.
● When the drivers foot is on the brake pedal, neither the brake control nor the alert by the system operates.
● When the Intelligent Cruise Control system is set, the DCA system will be cancelled.

Approach warning

due to rapid deceleration of that vehicle or if another vehicle cuts in, the system warns the driver with the chime and DCA system display.

Decelerate by depressing the brake pedal to maintain a safe vehicle distance if:

● The chime sounds.
● The vehicle ahead detection indicator blinks.

The warning chime may not sound in some cases when there is a short distance between vehicles.

Some examples are:

● When the vehicles are traveling at the same speed and the distance between vehicles is not changing
● When the vehicle ahead is traveling faster and the distance between vehicles is increasing
● When a vehicle cuts in near your vehicle The warning chime will not sound when your vehicle approaches vehicles that are parked or moving slowly.

NOTE:

NOTE:
The approach warning chime may sound and the system display may blink when DCA sensor detects vehicles in other lanes A or objects on the side of the road A .

This may cause the DCA system to operate inappropriately. The sensor may detect these objects when the vehicle is driven on winding roads, narrow roads, hilly roads or when entering or exiting a curve. In these cases you will have to manually control the proper distance ahead of your vehicle.

Also, the sensor sensitivity can be affected by vehicle operation (steering maneuver or driving position in the lane) or traffic or vehicle condition (for example, if a vehicle is being driven with some damage).

Automatic cancellation

Condition A:

Under certain conditions, the Distance Control Assist system is automatically canceled. The chime will sound, the DCA system switch indicator light will turn off and a message will pop up:

The Distance Control Assist System is automatically cancelled when:

The Distance Control Assist System is automatically cancelled when:

● When the VDC system is turned off
● When the VDC or ABS (including the traction control system) operates
● When the SNOW mode switch is turned ON

Action to take:

When the conditions listed above are no longer present, turn the system off with the dynamic driver assistance switch. Turn the DCA system back on to use the system.

Condition B:

When the sensor area of the front bumper is dirty, making it impossible to detect a vehicle ahead, the DCA system is automatically canceled.

The chime sounds and the system warning light (orange) will come on and the Sensor Blocked indicator will appear.

Action to take:

If the warning light comes on, park the vehicle in a safe place, turn the engine off. Clean the sensor area of the bumper and then perform the settings again.

Condition C:

When the DCA system is not operating properly, the chime sounds and the system warning light (DCA orange) will come on.

Action to take:

If the warning light comes on, park the vehicle in a safe place. Turn the engine off, restart the engine, and turn on the DCA system again.

If it is not possible to set the system or the indicator stays on, it may indicate that the system is malfunctioning. Although the vehicle is still driveable under normal conditions, have the vehicle checked at an INFINITI retailer.

Sensor maintenance

How to handle the sensor:

The sensor for the DCA system is common with Intelligent Cruise Control and is located behind the front bumper.
